In the past few years, we have covered plenty of amazing Nixie tube gadgets here. The Chopper Motorcycle IN-14 Nixie Clock is also worth a look. It is made of metal and leather in a steampunk style. The clock has 12/24 time format. It can also show the date. It uses a K155ID1Nixie Driver.
The bad news? Something like this doesn’t come cheap. You can find it on eBay.
